4A to 4C are schematic diagrams of application scenarios of the protective door assembly of the present invention.

Taking the two- and three-pin protection door as an example, Figures 4A to 4C illustrate the movement of the protection door assembly when the plug is normally inserted. The three-pin part of the two- and three-pin protection door is driven by the E pole of the three-pin plug. FIG. 4A shows the initial state of the protective door assembly when no inserts or pins are inserted. At this time, under the action of the elastic member 30 , the protective door body 20 can block the jack holes on the jack panel 50 . The plurality of socket portions of the socket structure 21 of the protective door body 20 include a first socket portion 211 and a second socket portion 212 . The first socket portion 211 is provided with a first driving slope 2111 and a first through hole 2112. The second socket portion 212 is provided with a second driving slope 2121 and a second through hole 2122. The first driving slope 2111 is parallel or substantially parallel to the second driving slope 2121 . The first driving slope 2111 and the second driving slope 2121 can respectively block the two sockets 51 of the two sockets 51 on the socket panel 50 .

The socket structure 21 is further provided with a third socket part 213 and a fourth socket part 214. As shown in FIG. 1 , the third socket portion 213 of the protective door body 20 includes a third through hole, and the portion of the protective door body 20 close to the third through hole can block the corresponding socket on the socket panel 50 . The fourth socket portion 214 is formed by the edge of the protective door body 20, and the edge is shaped to fit with the corresponding insert blade of the plug to facilitate the insertion of the insert blade. The portion of the protective door body 20 close to the fourth socket portion 214 can block the insertion. corresponding jacks on the hole panel 50. Correspondingly, the protective door body also includes a third driving slope 2113 at a position corresponding to the E-pole jack of the three-pin jack 52 , which can block the E-pole jack of the three-pin jack 52 of the jack panel 50 . In the sliding direction of the protective door body 20, the first driving ramp 2111, the third driving ramp and the second driving ramp 2121 are arranged in sequence. The driving direction of the third driving ramp is the same as or opposite to the driving direction of the first driving ramp 2111. . The third driving slope can be designed in various ways. For example, as shown in FIG. 1 , the third driving slope 2113 and the first driving slope 2111 are respectively disposed on both sides of the first through hole 2112 and connected with the first driving slope. The inclined planes 2111 are arranged oppositely; for another example, a fifth socket part is further provided, and the third driving inclined plane is arranged at the fifth socket part.

If the protection door corresponds to If the socket is a compact socket, the fifth socket part can be arranged between the first socket part 211 and the second socket part 212. If the two-plug and three-plug sockets of the socket to which the protection door is applied are arranged separately up and down, then The fifth socket portion is provided on the same side of the first socket portion 211 and the second socket portion 212 .

When the second plug is inserted into the protective door assembly normally, the movement of the protective door assembly is as shown in Figure 4B. When the two plugs are initially inserted into the protective door assembly, the plugs abut against the first driving slope 2111 of the first socket part 211 and the second driving slope 2121 of the second socket part 212, protecting the two rotation axes of the door body 20 22 against the protective door base 10 . When the insert is inserted further downward, the insert drives the protective door body 20 to slide to the left. When the first through hole 2112 and the second through hole 2122 move below the second plug hole 51 of the jack panel 50, the second plug hole 51 moves downward. The blade of the plug can pass through the protective door assembly smoothly and be inserted into the socket of the socket.

When the three-pin plug is normally inserted into the protective door assembly, the movement of the protective door assembly is as shown in Figure 4C. When the three-pin plug is initially inserted into the protective door assembly, the E-pole blade of the three-pin plug abuts against the third driving slope 2113 of the first socket portion 211 . Since the insertion position of the E pole insert is located in the middle area of the protective door body 20 and in the middle between the two sockets of the two sockets 51, the two rotating shafts 22 of the protective door body 20 are in the middle of the three sockets. The E-pole insert of the plug is supported on the protective door base 10 . When the insert is inserted further downward, the insert drives the protective door body 20 to slide to the right. When the first through hole 2112 moves below the E-pole jack of the three-plug jack 52 of the jack panel 50, the three-plug plug The insert can smoothly pass through the protective door assembly and be inserted into the socket of the socket. This kind of protective door assembly not only makes the plug insertion smoother, but also drives the protective door body through the E-pole insert. With this design, the protective door body can block the E-pole jack, which is beautiful, difficult to get dust, and safer.
